Hi Alisair Thanks a lot for the notification. I do feel uncomfortable because a mapping implicitly entails a hierarchy now. (still have to check what this will mean for exactMatch - can I somewhere find the new statements in a comprehensive draft version ?) But maybe that is just my thinking pattern that needs to adapt. Within that pattern, the application I handle considers the mapped (matched) concepts to belong to 2 different concept-schema. So there is no hierarchy intended, just a matching. kr, Johan De Smedt. =================== -----Original Message----- From: public-esw-thes-request@w3.org [mailto:public-esw-thes-request@w3.org] On Behalf Of Antoine Isaac Sent: Thursday, 29 May, 2008 10:41 To: Alistair Miles Cc: public-esw-thes@w3.org; 'SWD WG' Subject: Re: [SKOS] ISSUE-44 (was: Suggestion for SKOS FAQ) Alistair Miles a écrit : > Hi all, > > The current SKOS Reference Working Draft [1] takes the following position. > > The property skos:broader is, by convention, used to assert a "direct" > hierarchical link between two concepts. > Note that this 'link' also include 'hierarchical mapping links' since skos:broadMatch is made a suproperty of skos:broader (which means that every assertion of skos:broadMatch entails one assertion of skos:broader). Somehow I feel like your text also fits the situation, even when the interpretation of 'hierarchical link' is made a bit different from what it was. But I wanted to flag the issue to people of the SKOS mailing list which might not have noticed this new resolution, eventually to get feedback from them.
